SUPPORT FOR SADDLES FOR CYCLES. l

SPECIFICATION forming part of Letters Patent No. 617,000, dated January3, 1899. Application filed December 28,1897. Serial No. 664,115. (Nomodel.)

To all whont it may concern:

Be it known that I, \VILLIAM BASIL \VIL- BERFORCE, a subject of theQueen of Great Britain, residing at Bognor, in the county of Sussex,England, have invented a new and useful Improvement in Supports for theSaddles of Cycles, (for which I have obtained a patent in Great Britain,No. 13,246, bearing date May 28, 1897,) of which the following is a fulland complete specification.

This invention relates to devices for sup porting bicycle-saddles; andit consists in the novel construction and combination of theparts,hereinafter fully described and claimed.

The drawing shows a sectional side View of the support.

A is a member, preferably tubular, which fits into the usual socket ofthe bicycle-frame in which the seat-pillar is placed.

B is a member, also tubular, which is pivoted to the upper part of themember A by a pin a and socket a, or in any other approved manner, andwhich extends forwardly of the pivot-pin a. A roller 1) is journaled inthe front end portion of the member B, and b is a cap which closes therear end of the member B. The saddle F is supported from the member B inany approved manner in front of its pivot-pin. A stop b is provided forpreventing the member B from descending too far in front.

0 is a spring arranged within the member B. The front end of the spring0 is connected with the upper part of the member A by a flexibleconnection D, such as a band or chain, which passes over the roller b.

E is a screwed bolt which passes through a hole in the cap Z) and isconnected to the rear end of the spring 0. E is an adj Listing-nut whichengages with the bolt E and bears against the said cap. The tension ofthe spring is adjusted by turning the adjusting-nut.

This support enables the saddle to adjust its inclination automaticallyto the position of the rider on various gradients and enables him toexert his strength to greater advantage in propelling the bicycle. Theinclination of the saddle increases as the rider increases the pressureon the pedals at the beginning of a hill, and therefore affords him abetter purchase or support.

WVhat I claim is 1. In a saddle-support, the combination, with a memberA carried by the frame, of a tubular member B pivoted to the member Aand extending forwardly thereof, a spring arranged in the member B, aguide at the front end of the member B, a flexible connection passingover the said guide and secured to the member A and the springrespectively, and a screw for varying the strength of the said spring,said screw being operatively connected with the said spring and with therear end portion of the member B, substantially as set forth.

2. A support for the saddles of velocipedes, consisting of a member Aadapted to be fixed to the frame of the machine, a tubular member Bpivoted to the top of the member A and extending forwardly, a spring 0located in the tubular member B, a band or chain connecting the frontend of the spring 0 with the member A near its upper end, the said bandor chain passing around a roller 6 carried by the forward end of themember B, a screwbolt E connected to the rear end of the spring 0 andpassing through a cap 1) closing the rear end of the tubular member B,and an adjusting-nut E mounted on the screw-bolt E as set forth.
